Description

Technical Field

[0001] The utility model relates to the technical field of measuring equipment, in particular to a shell of a laser ranging telescope. Background Art

[0002] The handheld laser rangefinder telescope has a thumb grip at the rear lower end of the outer shell due to the particularity of its holding method and internal functional components, so it is easier for users to hold and use it, making the grip more comfortable and stable.

[0003] However, this design has a thumb grip that is located close to the rear end wall, that is, closer to the human body during the use of the telescope, and the thumb grip is recessed inward, resulting in a groove formed between the shell body and the inner wall of the rear end, which is an undercut. The formation of an undercut in the shell will affect the demoulding of the product. The conventional practice is to thicken the inner wall so that the undercut position is flush with the wall thickness, so that the shell molding is in a perfect state. However, due to the particularity of the laser rangefinder telescope, the product is small and the undercut diameter is large. If the wall thickness is designed to be too thick, the product will shrink, thereby affecting the appearance of the product shell molding. Injection molded part shrinkage refers to the process of injection molding, due to the physical properties of the plastic and the temperature changes during the molding process, which leads to deviations in the size of the molded injection molded part, that is, shrinkage. Injection molded part shrinkage can affect the dimensional accuracy and appearance quality of the product, and may even cause the parts to fail to fit.

[0004] Therefore, there is an urgent need for a laser ranging telescope housing that can avoid the problem of increased shell wall thickness due to an inverted design, thereby affecting the appearance of the shell after molding. Utility Model Content

Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0048] The utility model provides a laser rangefinder telescope housing, comprising an integrally formed housing 1, a face shell 2 sleeved on the outside of the housing 1, an insert 3 fixed inside the housing 1, and a lens holder 4 fixed at the front end of the housing 1. An installation cavity is provided inside the housing 1, and the installation cavity is used to place the rangefinder telescope assembly. An opening for installing the lens holder 4 is provided at the front end of the housing 1, and a first through slot 18 and a charging port 81 for passing the telescope eyepiece are provided at the rear end of the housing 1, and the first through slot 18 is a circular through slot.

[0049] A thumb grip 11 is provided on the rear side of the housing 1. The thumb grip 11 is a curved groove, which makes the inner wall of the housing 1 bulge inwards. Therefore, an undercut 5 is formed between the rear end of the housing 1 and the bulge.

[0050] The insert 3 includes a flat plate 32 that fits against the inner wall of the rear end of the shell 1, a filling portion 31 arranged at the bottom of the flat plate 32 for filling the undercut 5, and side panels that are respectively arranged on opposite sides of the flat plate 32 and extend perpendicularly to the flat plate 32; the filling portion 31 extends along the outer edge of the bottom of the flat plate 32.

[0051] The filling portion 31 matches the shape of the undercut 5 so that the top surface of the filling portion 31 is consistent with the inner wall of the housing 1 .

[0052] The flat plate 32 is provided with a first through hole 34 corresponding to the charging port 81, so that the inwardly recessed side wall of the charging port 81 can be inserted into the first through hole 34, so that the flat plate 32 fits with the inner wall of the rear end of the shell 1, thereby filling the inner wall recess of the charging port 81 at the rear end of the shell 1, and at the same time, it can also improve the structural strength of the rear end of the shell 1.

[0053] A second through groove 33 is provided on the top of the flat plate 32. The second through groove 33 is a semicircular through groove. The second through groove 33 matches the shape of the first through groove 18 so that the insert 3 can fill the inner wall depression of the charging port 81 at the rear end of the shell 1 without blocking the first through groove 18 for installing the telescope eyepiece.

[0057] By placing the insert 3 at the position of the undercut 5 and then injection molding the shell 1, the wall thickness can be kept uniform to ensure the fluidity of the plastic. This can effectively avoid the problem of increasing the wall thickness of the shell 1 by a large amount in order to solve the problem of difficulty in demolding after the undercut 5 is produced during injection molding, thereby affecting the appearance of the shell 1 after molding.

[0058] During the injection molding, if the housing 1 has an undercut 5, the housing 1 cannot be completely demolded by only using a horizontal ejection mechanism arranged in one direction, and an inclined ejection mechanism needs to be designed inside the mold to demold the housing 1. After adding the insert 3, when the injection mold ejects the molded housing 1, there is no need to set up an additional inclined ejection mechanism, and the housing 1 can be ejected only by the horizontal ejection mechanism, which can save mold costs.

[0061] A plurality of slots 41 are provided along the circumference of the lens holder 4 , and a plurality of first buckles 16 matching the slots 41 are provided on the inner side of the front end of the shell 1 . The lens holder 4 is fixed to the front end of the shell 1 by providing the slots 41 and the first buckles 16 .

[0062] An annular sealing ring 7 is also provided between the lens holder 4 and the housing 1 , so that the lens holder 4 and the housing 1 are more tightly connected and the interior of the housing 1 is more tightly sealed.

[0063] The middle of the lens holder 4 is provided with a third through groove for mounting the lens, and the lens fixing ring 6 is provided in the third through groove. An annular groove 61 is provided along the circumference of the lens fixing ring 6, and a plurality of second buckles 17 matching the annular groove 61 are provided on the inner side surface of the third through groove, and the lens fixing ring 6 is fixed to the lens holder 4 by providing the annular groove 61 and the second buckles 17.

[0064] A charging port protection cover 8 is also provided at the rear end of the shell 1 , and the charging port protection cover 8 is buckled on the rear end of the shell 1 to protect the charging port 81 .

[0065] The utility model provides a laser rangefinder telescope housing.
